Selective Tissue Penetration of the Corneal Layers of Cyclosporin 2% Associated with Miglyol in Rabbits.

Cyclosporin A (CsA) is a drug used to prevent immune rejection in corneal transplantation. Most grafts performed today are endothelial grafts which are complicated with poor penetration of CsA into the endothelium due to its hydrophobicity. To improve CsA penetration into the corneal a new ocular formulation of CsA 2% with Miglyol was developed and is commercially available.

"Knife cut technique". A new way for intra ocular lens (IOL) explantation.

Purpose: We report a novel technique which enables to cut any kind of foldable lens and extract it using capsulorhexis forceps and a 1.2 mm single-use slit angled knife.

Methods: The technique consists in using the capsulorhexis forceps to mantain and stabilize the IOL in the anterior chamber, and while one hand holds the IOL in that way, the second hand introduces a 1.

Usefulness of Cerebrospinal Fluid Alzheimer's disease biomarkers in older patients: Evidence from a national multicenter prospective study.

Background: The use of cerebrospinal (CSF) biomarkers in the diagnosis of Alzheimer's disease (AD) has been gaining interest in clinical practice. Although their usefulness has been demonstrated, their potential value in older patients remains debated.

Objectives: To assess whether knowledge of the results of CSF AD biomarkers was associated with the same gain in diagnostic confidence in older adults > 80 than in younger patients.
